My invention relates particularly to hinges consisting of two partsconnected by a detachable pinorpintle;

.i One object is toprovide a hinge of this -kind that is simple inconstruction, inexpensive tomanufactureand durable inuse. P5

.Another object .is' to provide exp'an sible means to permitthe readyinsertion; of, the

YAnother object is to provide an; antifriction hingewith means forretaining the pin.

7 Still another object is to provide .a'. hinge that is characterized by'fewness of parts; and I p a through the knuckle. .This. may be of very*by: a minimum wearfonsaidparts inpuse.- a

. .Anothenobject is 'toprovide amonsti'ud tion which eliminates theicu'stomaryf lateral projection fof. the pinpthus permitting itsinsertion in any position of rotation.

Another object is to provide a construe 1. .120 tion which can be madeand assembled at aminimum cost.

In carrying out the invention in its preferred form, the antifrictiondevices are secured to one of the knuckles of the hinge by a thintubular memberwhich is provided with one or more resilient projectionsadapted to automatically engage any corresponding grooves in the pinwhen the pin is inserted. This tubular member is expansi- W .30 ble andis so disposed relative to it's associated parts as to permit suchexpansion in use.

The invention is susceptlble of many variations in detail and is broadlyapplicable to v structures such as shown in the Myers Patcuts 1309.461anl 1,484,610 and the Raymond Patents 1,639,633 and 1,639,634.

Fig. 1 shows one form of construction embodying my invention as appliedto a butt 7 hinge, one leaf being partially broken away.

Fig. 2 shows the pin removed. Fig. 3 shows one form of anchorage tube.

leaves 10 and I which re spectivelyv have knuckles 12, 13 and 14 on theonetside and 1 5, 16 on the other side. These knuckles'are provided withlongitudinal passages ,constituting a bore forthepin 17.-;1his pin may-be'provided,.'if* desired, with grooves such .as 18and 19,for thereception of lubricant.

The rhinge is also preferably". provided ,withtantifriction vdevicessuch as the ball bearing-. members 20 and 21 which arean- 50fChOI'BdfOI' instance'to one of the knuckles as i 13. bylrineans 'of a'tubular. split sleeve 22,

In the form of sleeve shown inflFig. 5,

spring tongues 31 are provided adapted to engage in a correspondinglylocated groove in the pin. Y

It will be seen therefore that in the forms shown the sleeve performsthe triple function of permitting ready insertion of the pin, of holdingone or more antifriction bearings vto the-knuckle and also ofresiliently holding the pin in place to pre'ventitsjris'ing.

If the projection'suc'h as23 is not sufiiciently resilient'to permit theinsertion of thepins, the sleeve must expand. In such case the passagethrough the knuckle should be large enoughto' permit the necessaryexpansion without permanently deforming the beads 23. r a
